The fabrication and electrical property characterization of a new class of carbon nanotube (CNT)–nitride nanocomposites have been reported in this work. Electrical property measurements clearly reveal obvious increases in the electrical conductivities confirming the formation of a true composite material with enhanced electrical characteristics. Morever, the CNT–nitride nanocomposite still retains the electrochemical stability of the nitride material in highly corrosive electrolytes. Nitridenanoparticle-attached CNTs are crucial for the formation and enhanced properties of the composite, which provide good combination and form bridges between CNTs and the nitride matrix to give CNT–nitride composites.
